FOIL DRIVE ASSIST MAX+
The Foil Drive Assist MAX+ takes everything the world loved about our most popular foil assist and evolves it into the latest Gen 2.5 class, turning up thrust, runtime and safety features to unlock autonomy across every foiling discipline.
Built around the same proven 43V power, tech and charging architecture as the Fusion, the MAX+ offers Foil Drive's most durable one-piece battery design, all while retaining the compact, lightweight and balanced package that made the original MAX so versatile.
Unlock smaller foils, smaller boards, more performance and a faster take-off, with more time on the water thanks to tilt-safety cut-off features that make this retrofit kit family friendly.
Riders can enjoy a sportier feel without compromising on thrust and boost thanks to the new FM+650 Battery (650Wh) — with an even smaller FM+430 Battery arriving in early 2027.

The team at Stonker is not only hardworking but also lovely. My experience with Jess and Ben was truly exceptional as they possess extensive knowledge about their products. Despite I was interstate, I communicated with them over the phone and received exemplary assistance. I am extremely satisfied with their services and highly recommend Stonker to others. I will certainly be a returning customer in the future.
